Glass-Film-Glass (GFG) is a type of touch panel construction in which the sensing film layer is placed between two sheets of glass—one on top and one on the bottom. This design combines the strength of glass with the flexibility of conductive film, creating a panel resistant to scratches, shocks, vibrations, and harsh environmental conditions. GFG panels are usually based on resistive (RTP) technology, but when paired with tempered or AR-coated glass, they can also be used in outdoor and industrial applications where standard film-based panels would quickly fail.
The GFG structure improves resistance to chemicals, moisture, and dust, while offering better optical clarity and much higher durability than traditional film-film panels. It is valued in HMI panels, military equipment, automation systems, and public transport. The main drawbacks are increased thickness and higher production costs, which are offset by exceptional durability and reliability.
